主として重要である。BACKGROUND OF THE INVENTION For the formulation of paints and adhesive coatings resistant to airborne chemicals and corrosion, in particular the formulation of coatings intended for pre-lasocar coating of metal sheets, an operation often referred to by the term "coil coating". Therefore, it is known to use vinylidene fluoride polymer. Paints of this type are applied as very thin coatings, generally no more than about 20 microns thick. Vinylidene fluoride polymers obtained by aqueous emulsion polymerization are usually required for the formulation of such paints based on vinylidene fluoride polymers. S

.. No. 05 6,63 No. 6 describes the production of polyvinylidene fluoride as fine (primary) particles with an average size of about 0.2 Gkr, suitable for the formulation of organosolvanis for the protection of metals. The method is described. This method consists of polymerizing vinylidene fluoride in an aqueous medium in the absence of emulsifiers using peroxydisulfate as an initiator. This method is particularly attractive because of its simplicity and because of the small number of polymerization components (essentially water, monomer and water-soluble initiator) required for its use. Nevertheless, it has been found that the polyphthovinylidene obtained by the above-mentioned prior art process results in paints and coatings of low gloss. For many applications in the field of coatings, especially coatings for pre-lacquering metal sheets, it is desirable to have a high gloss coating that is useful.

A method for producing vinylidene polymers, comprising: introducing a chain regulator into an initial aqueous charge for polymerization;
The above chain regulator is alkyl acetate (the alkyl group is 1
to 3 carbon atoms).

ッ化ビニリデンが生戒される。The amount of chain regulator used is not particularly critical. It, of course, depends on the molecular weight and therefore on the intrinsic viscosity that is intended to be imparted to the polymer. Generally, about 0.0% based on the monomers used. 5-3% by weight of regulator is used. Within this concentration range, the amount of regulator is advantageously chosen experimentally as a function of the polymerization conditions and the desired result. A generally preferred concentration range is 1-2% modifier based on the monomers used. In this concentration range, polyvinylidene fluoride having an intrinsic viscosity of about 0.12 to 0.005 g/l, measured at 25 DEG C. in dimethylformado, is acceptable.

ーの量に依存する。The amount of initiator used in the polymerization can vary within certain limits. Nevertheless, it is recommended to use at least 0.005 g per liter of aqueous phase and not more than 0.5 g per liter of aqueous phase. Initiator concentration is aqueous phase 1
Preferably, it is about 0.03 to 0.2 g per liter. The initiator may be present in whole or in part in the initial aqueous charge. According to a preferred embodiment of the invention, all the peroxydisulfate is gradually introduced into the charge during the course of the polymerization. Polymerization temperature is not critical. Nevertheless, it is advantageous for the polymerization temperature to be in the range of about 80-95°C. In the above temperature range, vinylidene fluoride is above its critical temperature (30.1"C), so that the operating pressure is essentially temperature dependent and the amount of monomer present in the polymerization vessel.

ない。For process efficiency reasons, the polymerization pressure is advantageously higher than 20 bar, preferably about 30 to 45 bar. It is regulated and maintained by the gradual introduction of vinylidene fluoride. The total amount of vinylidene fluoride introduced generally does not exceed 0.22 parts by weight per part by weight of water.
